Scientific Calculator
Trig, logs, exponents, and roots in one browser pad—aimed at coursework and technical estimates, not shopping math.
STEM problems rarely stop at four operators. This scientific calculator exposes sine, cosine, tangent, common and natural logs, powers, and roots so you can evaluate expressions without installing desktop software or hunting for a physical TI-style pad.
Degree versus radian mistakes are the classic trap; the page keeps mode choice visible so homework answers match what your syllabus expects. Parentheses and operator precedence follow standard mathematical order, which helps when you paste multi-part formulas from a textbook.
When you only need a tip or a unit swap, the basic calculator or unit converter will feel faster. Keep this page bookmarked for physics, chemistry, precalculus, and engineering homework that lean on transcendental functions.
How to use
- Set angle mode — Choose degrees or radians to match your problem set before you press any trig keys.
- Build the expression — Enter numbers, functions (sin, cos, tan, log, ln), and parentheses in the order written on paper.
- Apply powers and roots — Use exponent and root keys for squared terms, cube roots, or fractional powers.
- Evaluate — Press equals and compare the display with your expected magnitude—wrong mode often shows up as an absurd result.
- Reset for the next problem — Clear the display so residual values do not leak into the next expression.
- Escalate simple arithmetic elsewhere — For plain +/−/×/÷ only, the basic calculator has a larger keypad and fewer distractions.
Use cases
- Trig homework — Evaluate sin/cos expressions for geometry, precalculus, and introductory physics labs.
- Logarithmic scales — Convert between linear and log forms for pH, decibels, or growth models.
- Engineering estimates — Check powers, roots, and combined formulas before you commit values to a report.
Tips
- Confirm degree/radian mode every time you reopen the tab—browsers may reset UI state.
- Wrap compound arguments in parentheses so functions apply to the full expression.
- If a trig result is nonsense, the mode is wrong more often than the key sequence.
- Pair with the percentage calculator when a problem mixes ratios with scientific functions.
FAQ
Yes. It runs in the browser with no account required.
Evaluation stays on-device in the browser. You only enter numbers and operators—no documents involved.
Match your textbook or exam instructions. Most high-school geometry uses degrees; many calculus texts use radians.
It covers scientific evaluation, not full graphing or CAS features. Use dedicated graphing software when you need plots.
It can do that too, but the simpler calculator page is quicker for everyday totals.
Yes. Function keys wrap for smaller screens; landscape can help if you prefer wider rows.
